Looking at a BBS from a '73-'74 p/u to replace the lean burn carb on my '84 p/u. It has the auto choke, pull-off, cable type throttle connection, may end up having to use a kickdown cable, if and once I get it, I'll check out to see if the stock kick down linkage will work or not. The replacement has a 6218s number referenced. Will this carb work for what I'm doing, along with the other ignition mods?
 
Carbs in that era could be "pretty lean" If you have one off a D200 will help.
 
I originally went with a 77-78-ish Holley 1945 when I deleted lean burn on my 85. I have since built a fresh replacement engine which has the super 6 intake, and I happened across an nos Carter BBD a while ago so I'm gonna go with that.

The '74 BBS comes closest to direct drop-in; that's truck carb numbers 7044s and 7045s. (manual and automatic transmission); van carb numbers 6583s and 6584s. Pics here and here. The 6218s is a '71 Dodge truck carburetor, lacking the built-in throttle return spring and having the earlier-type throttle lever configuration, and no idle kicker solenoid. None of this is a dealbreaker; you can use dual external throttle return springs instead of one external + carb's internal, and you can adapt to the earlier throttle lever. See this thread for kickdown options, and here for how to hook up the fuel vapour canister.

SlantSixDan, Once I obtain an electronic distributor ('73-'76 non lean burn), I'm sure one can benefit by changing springs and weight slot length to "curve" it slightly. I understand a "good" curve for my short bed D150 automatic would need to be slightly different that say a '64 valiant due to mass of vehicle among a few other things like transmissions and diff ratios. Do you have any suggestions? I've seen a lot of discussion on curves for /6 powered A-Bodies.
 
Get with DusterIdiot over on slantsix.org; he makes \6 distributor advance curves walk, talk, dance, and sing.
